よる性能の低下があった。Whiskers such as polyoxymethylene have high electrical resistance, making them difficult to handle due to the generation of static electricity, and reducing performance due to clogging.
その為、粒子が小さく表面積の大きい導電篩カーボンや
炭素繊維、耐炎化繊維などの比較的電気抵抗の小さい材
料を使用する方法が提案されたが、多孔質材料が得られ
難く、見掛は密度も大きなものであり、その効果は十分
でなかった。Therefore, methods have been proposed to use materials with relatively low electrical resistance, such as conductive sieve carbon, carbon fiber, and flame-resistant fiber, which have small particles and a large surface area, but it is difficult to obtain porous materials, and the apparent density is was also large, and its effects were not sufficient.

Including weight%, the apparent density is 0.02-0.4g7 mouths3
It is characterized by:

輪状の炭素層から構成される気相成長法は本発明の効果
を発揮する上で好ましい。In the present invention, carbon whiskers are whiskers obtained by a substrate growth method in which a carbon source such as a hydrocarbon is heated on the surface of a carrier, or a vapor phase growth method in which a carbon source and a catalyst are heated in a gas phase to continuously generate carbon whiskers. Graphitized carbon fibers obtained by heat-treating these carbon fibers, or whisker-like ultrafine carbon fibers obtained by heat-treating these in an active atmosphere to introduce reactive groups onto their surfaces. Although the manufacturing method is not particularly limited, a vapor phase growth method in which a carbon layer is formed with a tree-ring-shaped cross section is preferable in order to achieve the effects of the present invention.

絡みが増加し発泡体形成加工が難しい上に、加工時のは
破砕により安定した性能が得られる。The aspect ratio of the carbon whiskers used in the present invention is 20
-1000, preferably 50-500. The aspect ratio is expressed as the ratio of the length to the diameter of the whisker, and is, for example, the average value of n-20 values that can be observed under magnification using a scanning electron microscope. If the aspect ratio is less than 20, the surface area will be relatively reduced, resulting in a decrease in adsorption performance.If the aspect ratio is more than 1000, the physical entanglement of the whiskers will increase, making it difficult to form a foam and making it difficult to process. Stable performance can be obtained by crushing the time.

本発明の発泡体は、炭素ウィスカーを少くとも５重量％

％以下の場合は、目的とする、良好な保液性、ろ過性が
得られない。又、炭素ウィスカーの含有量が増加するに
つれ保液性などが向上するが、反面、発泡加工性が減少
する為、双方の特性を考慮して含有量を選定すれば良い
。含有量の上限は特に規定しないが、好ましくは６０重
量％程度が良い。The foam of the present invention contains at least 5% by weight of carbon whiskers.
It is important that the content is preferably 10% by weight or more; if it is less than 5% by weight, the desired good liquid retention and filtration properties cannot be obtained. Furthermore, as the content of carbon whiskers increases, liquid retention properties and the like improve, but on the other hand, foaming processability decreases, so the content should be selected taking both characteristics into consideration. There is no particular upper limit to the content, but it is preferably about 60% by weight.

した場合には発現することのない特異な特性である。Furthermore, the content affects the compression properties of the resulting foam, and by using an appropriate content of carbon whiskers, a foam with extremely high elasticity can be obtained, which can be achieved when carbon particles are used. It is a unique characteristic that has no

、又、０．４より大きい場合は、保液性能が低下し、軽
い発泡体が得られない。The apparent density of the foam is determined from the volume and weight, but if it is less than 0.02, there will be too many voids within the foam, making it difficult to obtain a uniform foam and reducing filtration performance. Not only that, but the mechanical properties of the foam are also not good, and if it is larger than 0.4, the liquid retaining performance will deteriorate and a light foam will not be obtained.

For example, 1) chemical foaming method using a foaming agent, 2) mechanical foaming method using physical stirring, 3) dry foaming method using solvent evaporation,
4) Wet foaming method using solvent replacement, etc.

いだけでなく、保液性や電気抵抗特性にも問題がある。Comparative Example 7 In Example 1, a foam was obtained by adding potassium titanate whiskers (whiskers manufactured by Jinure Kagaku Co., Ltd.) having an aspect ratio of 65 instead of the carbon whiskers. As shown in Table 1, these whiskers not only have a higher apparent density than carbon whiskers, but also have problems with liquid retention and electrical resistance.

い。Comparative Example 8 A foam was obtained by adding Ketjenblack EC (conductive carbon manufactured by Lion Corporation) in place of the carbon whisker in the same manner as in the example. As for the properties, as shown in Table 1, although the electrical resistance properties are excellent, the density is apparently large and the liquid retention is not good.
